Stuck Sims?! Help

I found a way to finally get my game back to normal! Sims no longer stop or freeze, they can interact normally. After adding the mod, there is no error in using it for the time being. It is also possible to save the archive successfully.

All you need to do is find the location of your game, find the [Delta] folder, copy the DLC folder you have in it, paste it into [The Sims 4] folder, and replace the duplicate files. Once you enter the game, everything is normal.

Of course, you better back up the [The Sims 4] folder before trying it out, in case that doesn't work for you.

Happens to me on occasion, I queue actions and they just stand there... Super annoying! What I find (usually) helps is to pause my game (by pressing 0) and then resume it again - that usually kick starts the action queue 😃

Frequently. Some households more than others. But I am constantly using the resetsim cheat... sigh. It's a pain.

You said "after you add the mod"  What mod are you talking about?

All the mods that I used before, functional mods such as MC Center. And others hair, clothes, makeup mods.

Weirdly, I updated the game and had no issues. I played for about an hour, came back from 'vacation', and suddenly my sim was stuck on her command to go use the toilet. Wouldn't respond to anything, reset sim didn't work. Couldn't even click another sim. They all froze in their actions and I couldn't select a different sim to play. 

I messed with the game for like an hour. Took my mods out, repaired the game - did a few variations of that for awhile. Kept having the same problem. I ended up having to revert to my previous save and lost the hour I'd played. I was able to keep my mods in (minus the ones that actually do need updates). Very weird. Prior to this I had a problem out of nowhere with my sims freezing (and freezing everyone else) if anyone interacted with a bar. Didn't update, didn't download anything new. It randomly stopped happening after two real life days of play.

I have tried everything you all recommended and then some. 

I honestly just want to play ... I haven't played in two weeks and its starting to stress me out. I have been going through so much and just want one good thing to happen ... AHHHHHH 

Thank you for clearing that up. I am experiencing this too, although it hasn't become a problem, it is bugging me. I though, have updated my game and any mods that are updated, but when you have as many mods in my game as I do, sometimes it breaks after and update by EA. I had not heard of doing this, and plan to give it a try. It took me a bit to locate the folders you mentioned, mine were not in the same folder as yours, but I did locate them. I just wanted to be sure about what mods you were using. Mc Center is in mine also and numerous hair, clothes, makeup, etc. I will post my results later. 

I am sorry I forgot to update the thread, but after doing this, I still have this problem.
